ESP IoT Solution无法配置及编译的原因？怎么处理？

我按照文档下载了与使用的IDF对应版本的esp-iot-solution，但接下来选择目标芯片、编译都不行。我按照文档配置了环境变量：set IOT_SOLUTION_PATH=E:ESP32esp-iot-solution，回车之后命令行没有任何提示，不知道是否设置成功，在idf.py set-target esp32s2提示找不到环境变量IOT_SOLUTION_PATH，在idf.py build也提示了没有找到IOT_SOLUTION_PATH，控制台的输出信息如下，是否有其他更多错误还不知道。

IDF我下载的是目前最新版本，并且能够正常使用，里面的例程能够编译下载，在外部创建自己的项目代码也能够编译下载。唯独使用esp-iot-solution的时候就不行了。

请问这个该怎么解决？
